PATENT FFIC CHARLES MAIER, OF NEW YORK, N. Y.

ORGAN.

SPECIFICATION forming part of Letters Patent No. 655,880, dated August 14, 1900. Application filed March 14, 1900. Serial No.8.595. (N0 model.)

T0 at whom it may concern:

Be it known that I, CHARLES MAIER, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Organs, of which the following is a specification.

My invention relates to organs, and has for its principal object to produce an improved construction of wind-chest, which wind-chest may be effectively used in a portable organ. This wind-chest is designed to be embraced in the smallest possible compass and to be of great strength, and to contain, as compared with prior structures, a much larger feeder capacity. To this end I arrange the walls of the wind-chest in the form of a triangle, upon two sides of which the organ-pipes are carried. The three walls of this triangle are preferably hollow, and two of these walls may be suitably partitioned, as will be hereinafter described.

- My invention has for its further object to improve the general construction of organs, in particular portable organs, the essential features of the invention being set forth in the claims.

In the accompanying drawings I have shown a structure illustrating my invention, it being understood, however, that I do not limit myself to such structure, but that the same may be departed from without departing from the spirit of my invention.

In the drawings, Figure 1 is .a partiallybroken-away front elevation of a sufficient number of parts of an organ to illustrate my invention. Fig. 2 is a sectional view, the section being taken through one of the hollow walls of the wind-chest. Fig. 3 is a section taken on a vertical plane through a portion of one of the hollow walls of the wind-chest. Fig. 4. is a plan view of the organ; and Fig. 5 is a side elevation of the organ, partly in section, the section being taken on the line 5 5 of Fig. 1.

Instead of making the so-called soundingboard or top side of the wind-chest fiat I make the wind-chest of a triangular form, with the hollow base CL and the inclined sides I) c, which are likewise hollow. On the inner faces of the inclined sides I arrange the two feeder-bellows d e, which are suitably operated, as by the bell-=crank-lever organism f. The reservoir-bellows g are preferably arranged on the inner face of the hollow base of the wind-chest and receive air from the saidv hollow base. The organ-pipes h are mounted on the outer wall of the hollow inclined sides of the wind-chest and are carried in the upright pipes t" of the shoes i, secured to the wind-chest by inclined plates 1' and communicating with the interior of the hollow sides. These organ-pipes have their mouthsj arranged at progressively-iucreasing heights, so that the pipes, although very close together when viewed from above, have considerablymore speaking-room than they would have if they were arranged upon a horizontal surface with the same space between them, as in the latter case one month would speak right against the other and the speaking-room advantages given by mounting the organ-pipes on the inclined sides of the wind-chest would not be present. The large pipes of the organ are preferably mounted lower down than the smaller pipes h, and of the smaller pipes h the larger ones are located low down and the smaller ones higher up on the wind-chest, thereby properly locating the center of gravity of the parts. It will thus be seen that by reason of the features of construction so far described a very great feeder capacity is given by reason of the fact that the two feeder bellows, although occupying little ground-space, extend for a considerable distance up and down, so that great power can be produced in an organ which is considerably smaller than an organ having the same power hitherto produced.

I The next branch of the invention has reference to the manner in which the air is distributed. Each of the inclined hollow walls of the triangle is provided with a plurality of partitionsZ Z, (shown in the present instance as the chest-backbones,) which partitions divide the hollow sides into three channels on, o, and p and are shown as extending downwardly and terminating at the hollow base a.

Of these channels the channel 0 communi cates with the feeder-bellows d or e and re ceives air from the same and delivers it into the hollow base a and thence into the reser voir, the flow of air being governed by suitable pallets q r. The other channels m 19 2 ssassb Communicate with the hollow base and receive air from the collapsible reservoir g and conduct the said air to the organ-pipes 7b. The drawings further show an arrangement for controlling the admission of air to the organ-pipe from the keyboard. The lower end of each organ-pipe communicates with the channels, opening through the soundingboard or outer partition 0' of the hollow inclined sides of the wind-chest. Admission of air to each channel is controlled by a pneumatic-valve arrangement comprising a small bellows '6, provided with valves t and with lifting-springs t The outside of these pneumatic valves or bellows is exposed to the pressure of the air in the channels at 19. These bellows are collapsed by the wind-pressure in the channels or register-chests m and p by means of suitable pipes to, having outlets un der the control of individual keys '0, which pipes to pass through bung-bars w and conduct air fromthe interior of the bellows or pneumatic valves t. It will be understood that so long as the pneumatics, as I will hereinafter call them, are kept inflated the valves t will be seated. By touching a key "0 air will be permitted to escape from a pipe u, the pneumatics will be collapsed by the internal air-pressure in the channels m 1), and the organ-pipe controlled by the valve operated will be placed in communication with an air-channel at O1]).

The arrangement of the pneumatics is shown at the left of Fig. l and the arrangement of the organ-pipes is shown at the right of Fig. 4, the organ-pipes being preferably staggered, as shown, in order to provide a greater amount of speaking-room.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. In an organ, the combination with suitable pipes or sounding devices of a hollowwalled triangular wind-chest.

2. In an organ or other wind instrument, the combination of a hollowwalled wind-chest of a general triangular shape and feeder-bellows mounted upon the inner faces of the triangular wind-chest.

3. An organ provided with a hollow-walled wind-chest of a general triangular form,

feeder-bellows delivering into the said hollow walls and organ-pipes mounted upon the said walls and having their months at different levels, whereby the organ-pipes may be placed close together and at the sametimegood speaking-room is attained.

4. A hollow-walled wind-chest for organs of substantially-triangular form.

5. A hollow-walled wind-chest for organs of substantially-triangular :form combined with feeder-bellows mounted on the inner faces of the triangle and an air-reservoir, substantially as described.

6. A hollow-walled wind-chest for organs of substantially-triangular form, combined with organ-pipes mounted upon the sides of the triangle.

7. In an organ, the combination of a triangular support and organ-pipes mounted upon the said triangular support and having their months at different levels, whereby the said organ-pipes may be placed close together and the distance between the mouths of adjacent organ'pipes will be greater than their horizontal distance apart.

8. In a wind instrument, the combination of an air-reservoir, a wind-chest having inclined hollow sides, the said sides being partitioned, the space or spaces upon one side of the partition being connected to suitable feeder-bellows and the space or spaces on the other side of the partition being connected to the air-reservoir and to organ-pipes.

9. In an organ or other wind instrument, the combination of the wind-chest with inclined hollow walls, organ-pipes supported upon and communicating with the interior of the hollow walls and pneumatic organpipecontrolling valves tmounted in the hollow walls, substantially as described and for the purposes set forth.

10. In an organ, the combination with suitable organ-pipes, of a wind-chest having an inclined Wall receiving the organ-pipes,whereby greater speaking-room is secured and an extended space for the feeder-bellows provided.
